  • Ocean hot in days of dinosaurs, study finds

    Sometimes we make that first dash into the ocean on summer vacation and happily announce, "It's warm as bathwater." But a new study based on ancient sediments collected off South America indicates that the tropical Atlantic Ocean really did hit temperatures as high as 107 degrees Fahrenheit back when dinosaurs ruled. The finding, reported Friday by researchers from the Woods Hole Oceanographic Institution during the annual meeting of the American Association for the Advancement of Science, also estimates that carbon dioxide made up as much as six times more of the atmosphere at that time than it does today.

    A recently discovered fossilized footprint shows that dinosaurs once roamed in what is now a national park in Alaska, scientists said on Tuesday. The footprint, estimated to be 70 million years old, was discovered on June 27, the first evidence of dinosaurs ever found in Denali National Park and Preserve, the National Park Service said. The find was made by a University of Alaska Fairbanks student attending a field camp in the park. The three-toed track, six inches wide and nine inches long, appears to be from the left foot of a therapod, a class of two-legged predators, said Anthony...

    Nanuqsaurus hoglundi was the big little dinosaur find that nearly got left behind. Classified in a March study, the hobbit T. rex, barely two-thirds the size of its more famous relative, roamed the Arctic some 70 million years ago. It's the only tyrannosaur ever found outside temperate latitudes, rewriting our understanding of the animals' diversity... In 2006, Fiorillo's team was above the Arctic Circle, on Alaska's North Slope. The polar season for fieldwork is brief, and they were busy excavating horned dinosaurs.

  • Oldest Horned Dinosaur in North American Discovered

    Paleontologists working in southern Montana unearthed a 3-inch beaked skull with pointed cheeks, which they believe is the oldest definitive evidence of a horned dinosaur in North America. Though small, the skull helps fill gaps in the evolutionary history of horned creatures on this continent... Fossil remains of horned dinosaurs, called neoceratopsian, have been found throughout North America, but the fossil record of these creatures is incredibly limited further back in time. That's been a hang-up for paleontologists because the late Early Cretaceous period (roughly 113 to 105 million years ago) was a time of important diversification for horned dinosaurs....

    Who doesn't love a dinosaur flick? Well, paleontologists have a few fossil bones to pick with Jurassic World, the latest in a line of dinosaur movies that once bragged about its scientific credibility. The trailer for the new movie, a reboot of the popular 1990s Jurassic Park franchise, was released Tuesday and has already been viewed more than 14 million times on YouTube. Like the original movie, Jurassic World takes place in an island safari park, where tourists visit living dinosaurs cloned from ancient DNA—until one hybrid monster goes rogue. Despite global fervor among fans, dinosaur scientists are not thrilled...

    They may have been plant-eaters, but stegosaurs were no easy prey: Researchers have found the fossil remains of what might be a deadly wound inflicted by the creature's spiked tail. Stegosaur tails have been a matter of some debate. While paleontologists used to say they were only for decoration, recent studies have suggested that the spiked, dexterous tails were actually used in combat. In 2005, researchers reported that a non-fatal wound found in the fossil of an allosaur -- a fearsome predator of stegosaurus's age -- was most likely inflicted by a stegosaur tail. But it turns out that those...

    Geoscientists now overwhelmingly agree that a single large asteroid or comet impact, such as Chicxulub in the Yucatan peninsula of Mexico, could not have been the sole cause of the end-Cretaceous mass extinction. Instead, new research in both planetary/space science and multiple earth-science specialties reveals that concomitant volcanic activity and the associated climate and environmental changes were significant contributing factors in four of the five major mass extinctions in Earth history.

    The earliest known ancestor of modern-day birds took to the skies by gliding from trees using primitive feathered wings on their arms and legs, according to new research by a University of Calgary paleontologist. In a paper published in the journal Paleobiology, Department of Biological Sciences PhD student Nick Longrich challenges the idea that birds began flying by taking off from the ground while running and shows that the dinosaur-like bird Archaeopteryx soared using wing-like feathers on all of its limbs. "The discussions about the origins of avian flight have been dominated by the so-called 'ground up' and 'trees down'...

    Fossil hunters in China have discovered what may be one of the weirdest prehistoric species ever seen -- a four-winged dinosaur that apparently glided from tree to tree. The 128-million-year-old animal -- called Microraptor gui, in honor of Chinese paleontologist Gu Zhiwei -- was about 2 1/2 feet long and had two sets of feathered wings, with one set on its forelimbs and the other on its hind legs. Exactly where the creature fits into the evolution of birds and dinosaurs is not clear. But researchers speculated that it developed around the same time as or even later than...

    The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur. Scientists say the beast had flat, paddle-like feet and nostrils on top of its crocodilian head that would allow it to submerge with ease. The research is published in the journal Science. Lead author Nizar Ibrahim, a palaeontologist from the University of Chicago, said: "It is a really bizarre dinosaur - there's no real blueprint for it.

    The collective noun is a terror of tyrannosaurs: a pack of the prehistoric predators, moving and hunting in numbers, for prey that faced the fight of its life. That tyrannosaurs might have hunted in groups has long been debated by dinosaur experts, but with so little to go on, the prospect has remained firmly in the realm of speculation. But researchers in Canada now claim to have the strongest evidence yet that the ancient beasts did move around in packs. At a remote site in north-east British Columbia - in the west of Canada - they uncovered the first known...

    Want to find the nearest pterosaur? There's an app for that — or a database, at least. A newly developed website catalogs more than 1,300 specimens of extinct flying reptiles called pterosaurs, thus enabling users to map out the ancient creatures on Google Earth. The goal is to help researchers find trends in the evolution and diversity of these ancient winged reptiles. "Having a very specific database like this, which is just for looking at individual fossil specimens of pterosaurs, is very helpful, because you can ask questions that you couldn't have answered with bigger databases [of more animals]," said...

Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus. Scientists believe it is a new species of titanosaur - an enormous herbivore dating from the Late Cretaceous period. A local farm worker first stumbled on the remains in the desert near La Flecha, about 250km (135 miles) west of Trelew, Patagonia.

    CHENNAI, India (Reuters) – Geologists have found a cluster of fossilized dinosaur eggs, said to be about 65 million years old, in a village in the southern Indian state of Tamil Nadu, according to media reports. > The clusters were under ash from volcanic eruptions on the Deccan plateau, which geologists said could have caused the dinosaurs to become extinct. >
  • Giant Impact Near India -- Not Mexico -- May Have Doomed Dinosaurs

    Boulder, CO, USA -- A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago. Sankar Chatterjee of Texas Tech University and a team of researchers took a close look at the massive Shiva basin, a submerged depression west of India that is intensely mined for its oil and gas resources. Some complex craters are among the most productive hydrocarbon sites on the planet. Chatterjee will present his research at...
  • Smithsonian’s dinosaur hall to close April 28 for five-year renovation

    More than 65 million years after they went extinct, dinosaurs are about to disappear again — at least from public view in Washington. The Smithsonian’s National Museum of Natural History said Friday that its high-traffic dinosaur hall will close April 28 for a previously announced $48 million makeover. Most of the popular specimens won’t reappear until 2019, when the Fossil Hall at the world’s second-most-visited museum is reopened.

    The New York Times ^ | 16 Dec 2013 | Kenneth Chang
    A dinosaur hobbyist who made his name as a Microsoft multimillionaire published a scientific paper on Monday alleging “serious errors and irregularities” in dinosaur research involving some of the world’s top paleontologists. The research, some of it dating to the 1990s, analyzed skeletons of different ages to estimate how quickly dinosaurs grew. For example, a 2001 paper, published in the journal Nature, estimates that the giant dinosaur Apatosaurus had a growth spurt of 12,000 pounds in a year. The papers, particularly a 2004 paper in Nature on the growth of Tyrannosaurus Rex, were influential in offering an explanation for why...
  • The Mystery of Lizard Breath: One-Way Air Flow May Be 270 Million Years Old

    Air flows mostly in a one-way loop through the lungs of monitor lizards -- a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study. The findings -- published online Dec. 11 in the journal Nature -- raise the possibility this breathing pattern originated 270 million years ago, about 20 million years earlier than previously believed and 100 million years before the first birds. Why remains a mystery. "It appears to be much more common and ancient than anyone thought," says C.G. Farmer, the study's senior author and an associate professor of biology...
  • What preserved T. rex tissue? Mystery explained at last

    The controversial discovery of 68 million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to newly published research, iron in the dinosaur's body preserved the tissue before it could decay. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive for millennia. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana.

    Each poo is a time capsule to the dawn of the dinosaurs. A gigantic "communal latrine" created at the dawn of the dinosaurs has been unearthed in Argentina. Thousands of fossilised poos left by rhino-like megaherbivores were found clustered together, scientists say. The 240-million-year-old site is the "world's oldest public toilet" and the first evidence that ancient reptiles shared collective dumping grounds. The dung contains clues to prehistoric diet, disease and vegetation says a study in Scientific Reports. Continue reading the main story [snip]
  • Newfound "King of Gore" Dinosaur Ruled Before T. Rex

    A newly discovered "King of Gore" tyrannosaur pushes back the origins of T. rex's terrifying family tree to at least 80 million years ago, report paleontologists. Lythronax argestes (which literally means "Gore King from the Southwest") once stalked the shores of western North America in search of prey. It sported the same short snout, broad teeth, front-facing eye, and unimpressive forearms as Tyrannosaurus rex, which lived around 68 million years ago. (Related: "Did the Real T. rex Resemble the One in Jurassic Park?") At 24 feet (7.3 meters) long and weighing about 2.5 tons, the 80-million-year-old Lythronax (pronounced LYE-thro-nax) lacked...

    EDMONTON - Experts are calling a dinosaur fossil unearthed in northern Alberta this week one of the “most complete finds in this part of the world in a long time.” Brian Brake, executive director of the Philip J. Currie Dinosaur Museum, said the fossilized remains of a hadrosaur were discovered at an energy company’s work site near Spirit River. Officials from the pipeline firm contacted the museum, which sent paleontologists to assess the find. “What we have is a totally composed tail,” Brake said. “It’s beautiful.” The Currie Museum contacted its counterparts at the Royal Tyrrell Museum in Drumheller, which...

    For most of us, "pterodactyls" are imagined as large, vicious and ugly gargoyles with lanky limbs, leathery wings and jaws lined with savage teeth, the sort of disreputable brutes we find in Arthur Conan Doyle's The Lost World, the Jurassic Park franchise – even a recent episode of Doctor Who. Such works suggest we should think ourselves lucky that these flying reptiles – some of which measured 10 metres across the wings and stood as tall as giraffes – were confined to landscapes populated by equally terrible dinosaurs, marine reptiles and turbulent volcanoes during a time known as the Mesozoic...

    It's well known that the dinosaurs were wiped out 66 million years ago when a meteor hit what is now southern Mexico but evidence is accumulating that the biggest extinction of all, 252.3m years ago, at the end of the Permian period, was also triggered by an impact that changed the climate. While the idea that an impact caused the Permian extinction has been around for a while, what's been missing is a suitable crater to confirm it. Associate Professor Eric Tohver of the University of Western Australia's School of Earth and Environment believes he has found the impact crater...
